● OPERATING INSTRUCTIONS ●
CLEANING
Instructions:
• Switch off the power supply or turn off the breaker before cleaning.
• Be careful not to touch the metal parts with your hands.
• Do not use benzine, thinner, polishing powder, or insecticide.
Air fi lter (Nano platinum fi lter)
• Clean every 2 weeks
• Remove dirt by a vacuum cleaner, or rinse with water.
• After washing with water, dry it well in shade.
What is “Nano platinum fi lter”?
Nano platinum is a ceramic particle that includes a platinum nanoparticle.
The particles are incorporated into the fi lter material, which results in providing semi-permanent antibacterial and deodorizing characteristics for the
fi lter. Nano platinum surpasses the catechin (a biofl avonoid that is found
in green tea) in performance. Nano platinum fi lter uses this compound not
only to improve air quality but also to eliminate bacteria and viruses. This air
fi lter has a semi-permanent lasting effect even after washing it with water.
• Use only diluted mild detergents.
• Do not expose parts to direct sunlight, heat, or fi re to dry.
• Do not use water hotter than 122°F (50°C).
Air cleaning fi lter
(Electrostatic anti-allergy enzyme fi lter,
blue)
Every 3 months:
• Remove dirt by a vacuum cleaner.
When dirt cannot be removed by vacuum cleaning:
•
Soak the fi lter and its frame in lukewarm water before rinsing it.
•
After washing, dry it well in shade.
Every year:
• Replace it with a new air cleaning
fi lter for best performance.
• Parts Number MAC-2330FT-E
Install all tabs of the air fi lter.
and

(Deodorizing fi lter, black)
Every 3 months:
• Remove dirt by a vacuum cleaner, or soak the framed fi lter in lukewarm
water 86 to 104°F [30 to 40°C] for about 15 minutes. Rinse well.
• After washing, dry it well in shade.
• Deodorizing feature recovers by cleaning the fi lter.
When dirt or smell cannot be removed by cleaning:
• Replace it with a new air cleaning fi lter.
• Parts Number MAC-3000FT-E
Important
• Clean the fi lters regularly for best performance and to
reduce power consumption.
• Dirty fi lters cause condensation in the air conditioner
which will contribute to the growth of fungi such as
mold. It is therefore recommended to clean air fi lters
every 2 weeks.

WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Even if these items are checked, when the unit does not recover from the
trouble, stop using the air conditioner and consult your dealer.
Symptom Explanation & Check points
Indoor Unit
The unit cannot be operated. • Is the breaker turned on?
The horizontal vane does not
move.
The unit cannot be operated for
about 3 minutes when restarted.
Mist is discharged from the air
outlet of the indoor unit.
The swing operation of the HORIZONTAL VANE is suspended for a
while, then restarted.
When SWING is selected in
COOL/DRY/FAN mode, the
lower horizontal vane does not
move.
The airfl ow direction changes
during operation.
The direction of the horizontal
vane cannot be adjusted with
the remote controller.
The operation stops for about
10 minutes in the heating
operation.
The unit starts operation by
itself when the main power is
turned on, but hasn’t received
sign from the remote controller.
The two horizontal vanes touch
each other. The horizontal
vanes are in an abnormal position. The horizontal vanes do
not return to the correct “close
position”.
The indoor unit discolors over
time.
• Is the power supply plug connected?
• Is the ON timer set? Page 9
• Are the horizontal vane and the vertical vane
installed correctly?
• Is the fan guard deformed?
• When the breaker is turned on, the horizontal
vanes’ position will be reset in about a minute.
After the reset has completed, the normal horizontal vanes’ operation resumes. The same is
true in the emergency cooling operation.
• This protects the unit according to instructions
from the microprocessor. Please wait.
The cool air from the unit rapidly cools moisture
•
in the air inside the room, and it turns into mist.
• This is for the swing operation of the HORIZONTAL VANE to be performed normally.
• It is normal that the lower horizontal vane does
not move when SWING is selected in COOL/
DRY/FAN mode.
• When the unit is operated in COOL or DRY
mode, if the operation continues with air blowing down for 0.5 to 1 hour, the direction of the
airfl ow is automatically set to upward position
to prevent water from condensing and dripping.
• In the heating operation, if the airfl ow temperature is too low or when defrosting is being
done, the horizontal vane is automatically set
to horizontal position.
• Outdoor unit is in defrost.
Since this is completed in max.10 minutes,
please wait. (When the outside temperature is too
low and humidity is too high, frost is formed.)
• These models are equipped with an auto
restart function. When the main power is
turned off without stopping the unit with the
remote controller and is turned on again, the
unit starts operation automatically in the same
mode as the one set with the remote controller just before the shutoff of the main power.
Refer to “Auto restart function” page 6 .
Perform one of the following:
Turn off and on the breaker. Make sure the horizon-
•
tal vanes move to the correct “close position”.
• Start and stop the emergency cooling operation
and make sure the horizontal vanes move to the
correct “close position”.
• Although plastic turns yellow due to the infl uence
of some factors such as ultraviolet light and
temperature, this has no effect on the product
functions.
Multi system
The indoor unit which is not
operating becomes warm and a
sound, similar to water fl owing,
is heard from the unit.
When heating operation is
selected, operation does not
start right away.
• A small amount of refrigerant continues to fl ow
into the indoor unit even though it is not operating.
• When operation is started during defrosting of
outdoor unit is done, it takes a few minutes (max.
10 minutes) to blow out warm air.
Outdoor Unit
The fan of the outdoor unit does
not rotate even though the compressor is running. Even if the
fan starts to rotate, it stops soon.
Water leaks from the outdoor
unit.
White smoke is discharged from
the outdoor unit.
• When the outside temperature is low during
cooling operation, the fan operates intermittently
to maintain suffi cient cooling capacity.
• During COOL and DRY operations, pipe or pipe
connecting sections are cooled and this causes
water to condense.
• In the heating operation, water condensed on
the heat exchanger drips down.
• In the heating operation, the defrosting operation
makes ice forming on the outdoor unit melt and
drip down.
• In the heating operation, vapor generated by the
defrosting operation looks like white smoke.
Symptom Explanation & Check points
Remote controller
The display on the remote
controller does not appear or it
is dim. The indoor unit does not
respond to the remote control
signal.
• Are the batteries exhausted? Page 3
• Is the polarity (+, -) of the batteries correct?
Page 3
• Are any buttons on the remote controller of other
electric appliances being pressed?
Does not cool or heat
The room cannot be cooled or
heated suffi ciently.
The room cannot be cooled
suffi ciently.
The room cannot be heated
suffi ciently.
Air does not blow out soon in
the heating operation.
• Is the temperature setting appropriate?
Page 6
• Is the fan setting appropriate? Please change
fan speed to High or Super High. Page 7
• Are the fi lters clean? Page 11
• Is the fan or heat exchanger of the indoor unit
clean?
• Are there any obstacles blocking the air inlet or
outlet of the indoor or outdoor unit?
• Is a window or door open?
• It may take a certain time to reach the setting
temperature or may not reach that depending on
the size of the room, the ambient temperature,
and the like.
• When a ventilation fan or a gas cooker is used
in a room, the cooling load increases, resulting
in an insuffi cient cooling effect.
• When the outside temperature is high, the cooling
effect may not be suffi cient.
• When the outside temperature is low, the heating
effect may not be suffi cient.
• Please wait as the unit is preparing to blow out
warm air.
Airfl ow
The air from the indoor unit
smells strange.
• Are the fi lters clean? Page 11
• Is the fan or heat exchanger of the indoor unit
clean?
• The unit may suck in an odor adhering to the
wall, carpet, furniture, cloth, etc. and blow it out
with the air.
Sound
Cracking sound is heard. • This sound is generated by the expansion/con-

absorbed from the drain hose by turning on the
range hood or the ventilation fan, making water
fl owing in the drain hose to spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
• This is the switching sound in turning on/off the
fan or the compressor.
• This is the sound of refrigerant or condensed
water fl owing in the unit.
• This is the sound when the fl ow of refrigerant
inside the unit is changed.
Timer
Weekly timer does not operate
according to settings.
The unit starts/stops the operation by itself.
• Is the ON/OFF timer set? Pages 9, 10
• Transmit the setting information of the weekly
timer to the indoor unit again. When the information is successfully received, a long beep will
sound from the indoor unit. If information fails to
be received, 3 short beeps will be heard. Ensure
information is successfully received. Page 10
• When a power failure occurs and the main power
turns off, the indoor unit built-in clock will be
incorrect. As a result, the weekly timer may not
work normally.
Be sure to place the remote controller where
the signal can be received by the indoor unit.

• Is the weekly timer set? Page 10
In the following cases, stop using the air conditioner and consult your dealer.
• When water leaks or drips from the indoor unit.
• When the operation indicator lamp blinks. Except for when the lamp of a multi
unit blinks while the unit is on standby.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic ON/
OFF type fl uorescent lamp (inverter-type fl uorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An amplifi er may be required for the affected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.
